Screen panels are the part of shale shaker or hydrocyclone separators, mud cleaner. They are filter plates for solid removal. What is difference among them?
In solids control system, shale shaker is the first phase equipment to remove drilled cuttings or solid particles. Screen panels are the direct filtration material on shakers. The screens vary for different designed shaker. Such as the pre-tensioned framed shaker screen panel, the hook strap screen, and so on
The screen mesh size will be coarse, relatively to screens on further equipment. Kindly suggest screen openings equal or coarser than API120. We know, based on theory, shale shaker will filter solid larger than 100microns out of drilling fluid. And cater for flow rate demand, the screen panels should not be too fine
Screen panels for mud cleaner
Hydrocyclone separators including the desander, desilter. Desander is used to separate particles larger than 45 microns, while desilter get rid of solid larger than 15 microns. They are the 2nd and 3rd phase solids control equipment
For desander and desilter, if we design downstream shaker screen we can configure mini bottom shaker or the commonly sized shakers. Difference including screen area and installation way. The screens can be downside tension or the common screen panels
Mud cleaner is also referred as mud conditioner or 3 in 1 for drilling mud solids control. It's integration of hydrocyclone desander, desilter and shale shaker. There is only one difference between downstream screen and shaker screen, the mesh size
We know shale shaker for solids control request coarse separation. Mud cleaner is used to remove much finer solids. Thus the downstream screen should be selected much finer. Kindly suggest API 200 or smaller opening. Then mud cleaner will help us make disposal more dry and separate the particles as more as possible after separated by cones and previous equipment
The screen panels for mud cleaner including framed, hook strap type. Same as our shale shakers. Please feel free to contact Aipu solids control for more detail or any question
Hard frame shaker screen is the screen panel with steel frame or support steel frame at backside. Upper tensioned screen is the hook strip screen.
Nowadays, at oilfield use, there are hundreds of shaker screens. For hard frame screen pane, popular ones are NOV Cobra series, VNM series, VSM series, LCM series, DP258 series, and so on. Black Thunder, 50, 500, 5000 etcetera series from FSI. KPT series from KEMTRON. Also many other models shaker screen, such as the Vortex, and so on
We usually make screen stick or adhere on punched plate welded on steel tubes. Punched plate can be with square hole and hexagonal holes. However, more and more clients prefer our square holes with thinner beam between holes for larger filtration area and conductance
Hard frame shaker screen
Prior to sticking screen on hard frame, we'll do pre-tension on screen cloth. Such operation will lead better appearance and enhance filtration efficiency. Also prevent possible failure caused by loose cloth.
We know it's hook strip screen. It can be soft hook strip or hard hook strip. The soft hook strip screen can be used on normal large shale shaker. Also the mini bottom shaker on desander or desilter will use the downside tension screen, it is soft hook strip screen.
The hard hook strip screen we'll call it as flat panel screen. The punched holes on panel can be square, rectangular and hexagonal as well. But the soft hook will be diamond shape.
Upper tension screen panel
It will be tensed by draw bar with tension bolts tensed. If we use the tension screen for mini shaker on hydrocyclone separator, we will tensioned screen under the screen cloth by locking on small shaker deck.
Please refer to our previous post on hook strip screen installation. Or you can call us anytime if you need more details
Aipu is proud to say we are able to provide almost replacement screen for oilfield shakers. Including the hard frame shaker screen and upper tension screen. Please when you have demand send us detail specs and what you have in hand
Aipu will quote you ASAP with the picture for your insurance confirmation. No matter for shale shaker or for mud cleaner, even for mini bottom shaker on hydrocyclone desander, desilter
